Meaning and Message - Introducing Semiotics
i
Semiotics is the theory that investigates how sign systems work, and how they can use images and symbols to represent a word or phrase. For example, if you see a sign with a graphic of children crossing a road, you understand that it means ‘children crossing’.
On the opposite, some signs can be read differently depending on the person who is reading it; and certain factors such as age, birth place and their circumstances. Signs can also include many alternate ways of communicating a message. A sign can use spoken or written language, it can also use codes, gestures, images, objects or sounds.
There are 3 types of signs that can be read by the brain, these signs are;
Icon - A sign that directly shows the psysical form of what it stands for.
Index - A sign which implies the object that is being represented.
Symbol - A sign with a conventional or arbitray relation to the object.
